The Relative Accuracy of Different Methods for Measuring Mind Wandering Subtypes: A Systematic Review

Brain and Behavior, Volume 15, Issue 8, August 2025.
How do we accurately measure mind wandering? This review compares five methods: from self‐reports (prone to bias) to brain scans (precise but expensive). No single method captures all aspects, so we propose the MAMW framework—a unified approach combining strengths of each technique.

Molecular Gas Kinematics in Barred Spiral Galaxies [PDF]

The Astrophysical Journal, 1999
To quantify the effect that bar driven mass inflow can have on the evolution of a galaxy requires an understanding of the dynamics of the inflowing gas. In this paper we study the kinematics of the dense molecular gas in a set of seven barred spiral galaxies to determine which dynamical effects dominate.

Dissecting Bar-induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications

The Astrophysical Journal
We analyze bars formed in N -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuthal components of stellar velocities, and the impact of bars on rotation ...

Effects of Magnetic Fields on Gas Dynamics and Star Formation in Nuclear Rings

The Astrophysical Journal, 2023
Nuclear rings at the centers of barred galaxies are known to be strongly magnetized. To explore the effects of magnetic fields on star formation in these rings and nuclear gas flows, we run magnetohydrodynamic simulations in which there is a temporally ...

C13‐Deacylase from Nocardioides albus Resp. Streptomyces sp., Catalyzing Side Chain Hydrolysis on the Taxane Core

ChemCatChem, Volume 17, Issue 15, August 7, 2025.
An enzyme that has been identified and characterized as capable of hydrolyzing paclitaxel (Taxol), a key anticancer drug derived from Pacific yew (Taxus brevifolia) has been identified. Molecular docking (MD) simulations map the catalytic triad and critical residues that drive substrate‐enzyme interactions. The findings indicate the catalytic potential

Comparison of Bar Formation Mechanisms. I. Does a Tidally Induced Bar Rotate Slower than an Internally Induced Bar?

The Astrophysical Journal
Galactic bars can form via the internal bar instability or external tidal perturbations by other galaxies. We systematically compare the properties of the bars formed through the two mechanisms with a series of controlled N -body simulations that form ...

Secular Evolution and the Formation of Pseudobulges in Disk Galaxies

, 2004
We review internal processes of secular evolution in galaxy disks, concentrating on the buildup of dense central features that look like classical, merger-built bulges but that were made slowly out of disk gas. We call these pseudobulges. As an existence

The Shape and Figure Rotation of NGC 2915's Dark Halo [PDF]

, 1999
NGC 2915 is a blue compact dwarf galaxy with a very extended HI disk showing a short central bar and extended spiral arms, both reaching far beyond the optical component.

Analysis, Testing, and Design of a UHF and HF Peer‐to‐Peer Communication System for the Europan Cryosphere

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract This study presents a validated design of a dual‐band wireless relay system of “pucks” for through‐ice communication between a cryobot and a surface lander during a future exploration of the Europan cryosphere. The design of a terrestrial demonstration system and the results of a 103 m through‐ice system test in a relevant environment near ...
